Automatic Accuracy Estimation for Audio Transcriptions

1. A method of assigning a confidence level to at least one axiom extracted from a text, comprising: determining a number of accurate words in text data based on a spell check function, wherein the text data are extracted from different sources; dividing a number of accurate words from the text data by a total number of words in the text data; assigning a greater weight to at least one word exceeding a predetermined number of characters as compared to at least one other word below the predetermined number of characters; automatically extracting, using natural language processing, from a knowledge base stored in a computer infrastructure, the at least one axiom, wherein the at least one axiom is associated with at least one word from the text data, and wherein the axiom comprises a computer-parsable definition of a relationship of data to at least one of the words in the text data; assigning a confidence level to the at least one axiom based on a result of the dividing and the assigning, wherein the confidence level is assigned based on an output of a Gaussian function applied to the result of the dividing and the assigning; receiving a query from a user device, wherein the query includes at least one word; matching the at least one word with the at least one axiom using the knowledge base; and providing the at least one axiom from the knowledge base to the user device based on the matching and the assigned confidence level.

2. The method of claim 1 , further comprising: comparing the text data to the data structure, wherein the data structure comprises a dictionary.

3. The method of claim 2 , further comprising: determining a number of inaccurate words in the text data based on the comparing.

4. The method of claim 2 , wherein the dictionary comprises a customer specific dictionary.

5. The method of claim 2 , wherein the dictionary comprises a dictionary of common language words.

6. The method of claim 2 , wherein the determining the number of inaccurate words comprises identifying a number of words not found in the dictionary.

7. The method of claim 1 , wherein a solution service provider provides a computer infrastructure operable to perform the method.

8. A system for assigning a confidence level to at least one axiom extracted from a text, comprising: a memory medium comprising instructions; a bus coupled to the memory medium; and an audio transcription tool coupled to the bus that when executing the instructions causes the system to: determine a number of accurate words in text data based on a spell check function, wherein the text data are extracted from different sources; divide a number of accurate words from the text by a total number of words in the text data; assign a greater weight to at least one word exceeding a predetermined number of characters as compared to at least one other word below the predetermined number of characters; automatically extract, using natural language processing, from a knowledge base stored in a computer infrastructure, the at least one axiom, wherein the at least one axiom is associated with at least one word from the text data, and wherein the axiom comprises a computer-parsable definition of a relationship of data to at least one of the words in the text data; assign a confidence level to the at least one axiom based on a result of the dividing and the assigning, wherein the confidence level is assigned based on an output of a Gaussian function applied to the result of the dividing and the assigning; receive a query from a user device, wherein the query includes at least one word; match the at least one word with the at least one axiom using the knowledge base; and provide the at least one axiom from the knowledge base to the user device based on the matching and the assigned confidence level.

9. The system of claim 8 , the an audio transcription tool coupled to the bus that when executing the instructions further causes the system to: compare the text data to the data structure, wherein the data structure comprises a dictionary; and determine a number of inaccurate words in the text data.

10. The system of claim 9 , wherein the dictionary comprises a customer specific dictionary.

11. The system of claim 9 , wherein the dictionary comprises a dictionary of common language words.

12. The system of claim 9 , wherein the determining the number of inaccurate words comprises identifying a number of words not found in the dictionary.

13. A computer program product for assigning a confidence level to at least one axiom extracted from a text, the computer program product comprising a computer readable hardware storage device, and program instructions stored on the computer readable hardware storage device, to: determine a number of accurate words in text data based on a spell check function, wherein the text data are extracted from different sources; divide a number of accurate words from the text data by a total number of words in the text; assign a greater weight to at least one word exceeding a predetermined number of characters as compared to at least one other word below the predetermined number of characters; automatically extract, using natural language processing, from a knowledge base stored in a computer infrastructure, the at least one axiom, wherein the at least one axiom is associated with at least one word from the text data, and wherein the axiom comprises a computer-parsable definition of a relationship of data to at least one of the words in the text data; assign a confidence level to the at least one axiom based on a result of the dividing and the assigning, wherein the confidence level is assigned based on an output of a Gaussian function applied to the result of the dividing and the assigning; receive a query from a user device, wherein the query includes at least one word; match the at least one word with the at least one axiom using the knowledge base; and provide the at least one axiom from the knowledge base to the user device based on the matching and the assigned confidence level.

14. The computer program product of claim 13 , the computer program product comprising a computer readable hardware storage device, and program instructions stored on the computer readable storage medium, to: compare the text data to the data structure, wherein the data structure comprises a dictionary; and determine a number of inaccurate words in the text data.

15. The computer program product of claim 14 , wherein the dictionary comprises a customer specific dictionary.

16. The computer program product of claim 14 , wherein the dictionary comprises a dictionary of common language words.

17. The computer program product of claim 14 , wherein the determining the number of inaccurate words comprises identifying a number of words not found in the dictionary.
